Recognition and Implementation of Cylinder QR Code

Abstract

Abstract:

Traditional QR code recognition algorithm is usually applied to the barcode printed on flat surface only, the barcode on cylinder, because of the distortion of 2D and

3D space, the recognition rate is low. The paper proposes a new method by adding auxiliary rectangles which is parallel to QR code outer contour for 2D space correction when the

background is relatively clear. After getting the 2D correction image, using area reduction for 3D space correction, it is implemented on the Android platform. The result shows

this method has high recognition rate.

Key words: QR code, cylinder, auxiliary rectangle, correction algorithm, Android
